3 Claims.

This invention relates to a buckle and has special reference to a buckle adapted to be adjustably associated with straps, bands and the like for the support of garments or other objects on the person.

prises a strap-receiving frame formed of sheet metal having a button-retaining opening, a portion I8 of the material bounding the opening being displaced in a all, the strap being preferably threaded for adjustable engagement with the buckle frame. It is readily apparent, of course, that various other uses could be mentioned in connection with buckles generally of the type adopted for use with supporting and supported members and that this invention therefore is not to be limited to the specific use herein described and illustrated.

In a buckle of the above noted type it is highly desirable to minimize if not actually prevent wear is ordinarily occasioned between the present invention contemplates the substantial elimination of this wear in the provision of a depending button-retaining loop, the material of which is displaced in such a manner as to present a rounded edge adjacent the button-supported member with a portion [8 ofv the loop bounding the opening thereof being displaced in a direction away from the button-supported member,

Other objects and advantages will hereinafter be more particularly pointed out, and for a more gether with the accompanying drawing, in which latter:

Figure 1 is a plan view of a buckle constructed in accordance with the teachings of this invention; r r

Fig. 2 is a sectional view on an enlarged scale taken on the line 22 of Fig. 1;

Fig. 3 is an enlarged sectional view similar to Fig. 2 showing an association ofthe buckle of the present invention with a fragmental portion of a supported and a supporting member;

Fig. 4 is a front elevational View of Fig. 3;

Fig. 5 is a perspective View of the buckle showing the rear face thereof; and

Fig. 6 is a plan sectional view taken on the line 6-6 of Fig. 1.

Referring now more particularly to the drawing, the buckle of the as comprising a. frame 9 preferably rectangular in shape comprising side bars l and l I connected by spaced cross bars l2. l3, l4 and I5. The cross bar l of the frame is shaped to define a buttonretaining loop I6, the button-receiving opening I! of which opens into the slot defined by the cross bars I4 and 15.

The buckle may be conveniently stamped or otherwise formed from sheet metal with the side bars and cross bars dished to form a so-called embossed frame as shown more particularly in Figs. 2 and 3 with the result that the buckle frame and relatively light gauge metal may be utilized while still producing a buckle of the desired strength.

The buckle illustrated and described above is of the type disclosed in the patent issued to Louis A. Erb, No. 1,999,166 issued April 23, 1935, and assigned to the assignee of the present invenopening forming the button-retaining loop, and with reference now more particularly to Fig. 3

away from a button-supported member IS, a

ber IS. The face of the button-retaining loop I8 is also provided with displaced portions or humps 30 lying substantially in the plane of an off-set portion 3| of the bar Hi to deflect the button 20 over the fold of the strap 22 folded about the bar M as tension is relieved on the strap 22. peripheralembossment 2! of the button-retaining loop is folded to present a rounded edge adjacent the button-supported member IS.

A pressure is alternately exerted and relieved on a strap 22 by movement of the wearer of the garment and the buckle alternately pulls and is relieved of its engagement with the button. Because of the play necessitated in affording a desired detachability between the buckle and the button, this alternate application and releasing of pressures between the supported and supporting members results in thetilting of the button and the supported member so that an engagement is had between the depending loop portion 16 of the buckle and the supported member. Such engagement usually produces undue wear where sharp and perhaps rough edges are presented between the depending loop portion of the material of the supported member adjacentthe button. The present invention provides the usual embossed portion of the loop to be turned in a manner to present a well rounded edge to minimize, if not substantially eliminate, any wear on the material of the supported member. Also by reason of the material of the member bounding the button-receiving opening being flared in a direction away from the supported member, a rounded surface is presented to the material of the supported member if any engagement is had therebetween.

While but a single embodiment of this invention is herein shown and described, it is to be understood that various modifications thereof may be apparent to those skilled in the art without departing from the spirit and scope of this invention and, therefore, the same is only to be limited by the scope of the prior art and the appended claims.

I claim:

1. A buckle for detachably securing a buttonsupported member to a strap or other supporting member comprising a strap-receiving frame formed of sheet metal having a button-retaining opening for receiving the shank of a button, and a flared portion bounding the button-retaining opening of said button-retaining loop and extending out of the normal plane of the frame in a direction away from the button-supported member.

2. A buckle for detachably securing a buttonsupported member to a strap or other supporting Vmember comprising a strap-receiving frame formed of embossed sheet metal and having a depending button-retaining loop for receiving the shank of a button, a flared portion bounding the button-retaining opening on the interior edge of said button-retaining loop and extending out of the normal plane of the frame in a direction away from the button-supported member, and a folded portion formed from the material of the embossment on the exterior edge of said button-retaining loop to present a rounded edge adjacent the button-supported member.

3. A buckle for detachably securing a buttonsupported member to a strap or other supporting member comprising a strap-receiving frame formed of sheet metal having a depending button-retaining loop for receiving the shank of a button, a rounded displaced portion of the buttonretaining loop extending in the direction of the button-supported member and presenting a blunt contact therewith, and a flared portion bounding the button-retaining opening of said buttonretainin'g loop extending out of the normal plane of the frame in a direction away from the buttonsupported member.
